Description

本開示は、コネクタおよびコネクタ装置に関する。 The present disclosure relates to connectors and connector devices.

例えば、通信用の信号が伝送されるシールド電線の端末に接続されたシールドコネクタとして、特開２０１８－６１８３号公報（下記特許文献１）に記載のものが知られている。このシールドコネクタは、雄コネクタとされており、雄型内導体と、誘電体を介して雄型内導体を囲む外導体とを有している。また、雄コネクタは、雌コネクタと嵌合可能とされている。雌コネクタは、雌型内導体と、雌型誘電体を介して雌側内導体を囲む雌側外導体を有している。雄コネクタと雌コネクタとが嵌合する際には、外導体が雌側外導体の外側に嵌合され、外導体と雌側外導体とが接続される。 For example, JP-A-2018-6183 (Patent Document 1 below) discloses a shield connector connected to a terminal of a shield electric wire through which communication signals are transmitted. This shield connector is a male connector and has a male inner conductor and an outer conductor surrounding the male inner conductor via a dielectric. Also, the male connector is matable with the female connector. The female connector has a female inner conductor and a female outer conductor surrounding the female inner conductor via a female dielectric. When the male connector and the female connector are mated, the outer conductor is fitted to the outside of the female outer conductor, and the outer conductor and the female outer conductor are connected.

特開２０１８－６１８３号公報JP 2018-6183 A

ところで、上記の雄コネクタは、外導体が雌側外導体の外側に嵌合する構成となっているため、外導体と雄型内導体との距離が、雌コネクタにおける雌側外導体と雌型内導体との距離に比べて大きくなっている。したがって、雄コネクタにおけるインピーダンスは、雌コネクタにおけるインピーダンスに比べて高くなり、雄コネクタと雌コネクタと間においてインピーダンスの不整合が生じることが懸念される。 By the way, since the above-mentioned male connector is configured such that the outer conductor is fitted to the outside of the female outer conductor, the distance between the outer conductor and the male inner conductor is the same as that of the female outer conductor in the female connector. It is larger than the distance from the inner conductor. Therefore, the impedance at the male connector is higher than the impedance at the female connector, and there is concern that impedance mismatch may occur between the male connector and the female connector.

本明細書では、互いに嵌合可能なコネクタ間においてインピーダンスの不整合が生じることを抑制する技術を開示する。 This specification discloses a technique for suppressing impedance mismatch between matable connectors.

本開示のコネクタは、電線の外周をシールド体で覆うケーブルに接続された状態で相手方コネクタと嵌合するコネクタであって、内導体と、外導体とを備え、前記内導体は、前記電線の芯線に接続された状態で前記相手方コネクタに設けられた相手方内導体に接続可能とされ、前記外導体は、大径筒部と、小径筒部と、シールド接続部とを有しており、前記シールド接続部は、前記シールド体に接続され、前記大径筒部は、前記相手方コネクタに設けられた筒状の相手方外導体が内部に嵌合可能な筒状に形成され、前記小径筒部は、前記大径筒部よりも小径の筒状に形成されると共に、前記内導体を収容している。 A connector of the present disclosure is a connector that is fitted to a mating connector while being connected to a cable whose outer circumference is covered by a shield body, and includes an inner conductor and an outer conductor, wherein the inner conductor is the outer conductor of the electric wire. The outer conductor has a large-diameter cylindrical portion, a small-diameter cylindrical portion, and a shield connection portion, and is connectable to a mating inner conductor provided in the mating connector while being connected to the core wire. The shield connecting portion is connected to the shield body, the large-diameter cylindrical portion is formed in a cylindrical shape into which a cylindrical mating outer conductor provided on the mating connector can be fitted, and the small-diameter cylindrical portion is , is formed in a cylindrical shape having a diameter smaller than that of the large-diameter cylindrical portion, and accommodates the inner conductor.

本開示によれば、互いに嵌合可能なコネクタ間においてインピーダンスの不整合が生じることを抑制できる。 According to the present disclosure, it is possible to suppress the occurrence of impedance mismatch between connectors that can be fitted to each other.

［本開示の実施形態の説明］
最初に本開示の実施形態を列挙して説明する。
（１）電線の外周をシールド体で覆うケーブルに接続された状態で相手方コネクタと嵌合するコネクタであって、内導体と、外導体とを備え、前記内導体は、前記電線の芯線に接続された状態で前記相手方コネクタに設けられた相手方内導体に接続可能とされ、前記外導体は、大径筒部と、小径筒部と、シールド接続部とを有しており、前記シールド接続部は、前記シールド体に接続され、前記大径筒部は、前記相手方コネクタに設けられた筒状の相手方外導体が内部に嵌合可能な筒状に形成され、前記小径筒部は、前記大径筒部よりも小径の筒状に形成されると共に、前記内導体を収容している。 [Description of Embodiments of the Present Disclosure]
First, the embodiments of the present disclosure will be enumerated and described.
(1) A connector that is fitted to a mating connector while being connected to a cable whose outer circumference is covered by a shield, comprising an inner conductor and an outer conductor, wherein the inner conductor is connected to the core wire of the electric wire. The outer conductor has a large-diameter cylindrical portion, a small-diameter cylindrical portion, and a shield connection portion, and the shield connection portion is connected to the shield body, the large-diameter tubular portion is formed in a tubular shape into which a tubular counterpart outer conductor provided in the counterpart connector can be fitted, and the small-diameter tubular portion is connected to the large-diameter tubular portion. It is formed in a cylindrical shape with a diameter smaller than that of the cylindrical portion, and accommodates the inner conductor.

大径筒部内に相手方外導体が嵌合されるものの、内導体は大径筒部よりも小径に形成された小径筒部内に収容されているから、相手方外導体と嵌合される大径筒部に比べて、内導体と小径筒部との間の距離を小さくできる。つまり、内導体と小径筒部との間の距離を、相手方内導体と相手方外導体との距離に近づけることにより、相手方コネクタとコネクタとの嵌合後に、相手方コネクタとコネクタとの間においてインピーダンスの不整合が生じることを抑制できる。 Although the counterpart outer conductor is fitted in the large-diameter tubular portion, the inner conductor is accommodated in the small-diameter tubular portion formed to have a diameter smaller than that of the large-diameter tubular portion. The distance between the inner conductor and the small-diameter cylindrical portion can be reduced compared to the portion. In other words, by making the distance between the inner conductor and the small-diameter cylindrical portion closer to the distance between the mating inner conductor and the mating outer conductor, the impedance between the mating connector and the connector is reduced after mating the mating connector and the connector. It is possible to suppress the occurrence of inconsistency.

（２）前記小径筒部と前記相手方外導体とは、同径に形成されている。小径筒部と相手方外導体とが同径とは、小径筒部の径寸法と相手方外導体の径寸法が同一の場合と、小径筒部の径寸法と相手方外導体の径寸法が同一でない場合であっても実質的に同一と認定しうる場合を含む。
小径筒部と相手方外導体とが同径となっているから、相手方コネクタとコネクタとの嵌合後に、相手方コネクタとコネクタとの間においてインピーダンスの不整合が生じることをさらに抑制できる。 (2) The small-diameter cylindrical portion and the counterpart outer conductor are formed to have the same diameter. The diameter of the small-diameter tubular portion and the counterpart outer conductor are the same when the diameter of the small-diameter tubular portion and the diameter of the counterpart outer conductor are the same, and when the diameter of the small-diameter tubular portion and the diameter of the counterpart outer conductor are not the same. This includes cases where it can be recognized as being substantially the same.
Since the small-diameter cylindrical portion and the mating outer conductor have the same diameter, it is possible to further suppress impedance mismatch between the mating connector and the connector after mating the mating connector and the connector.

（３）前記小径筒部は、前記大径筒部における前記相手方コネクタ側とは反対側の端部に連なっている。
大径筒部と小径筒部とが連なって一体となっているから、例えば、大径筒部と小径筒部とが別体に構成される場合に比べて、部品点数を低減できる。これにより、コネクタの組み立て作業性を向上させることができる。 (3) The small-diameter tubular portion continues to the end of the large-diameter tubular portion on the side opposite to the mating connector.
Since the large-diameter tubular portion and the small-diameter tubular portion are continuous and integrated, the number of parts can be reduced compared to, for example, the case where the large-diameter tubular portion and the small-diameter tubular portion are configured separately. Thereby, it is possible to improve the assembly workability of the connector.

（４）前記外導体は、第１外導体と、前記第１外導体に組み付けられる第２外導体とによって構成され、前記第１外導体は、前記大径筒部と、前記小径筒部とを有し、前記第２外導体は、前記シールド接続部と、前記小径筒部の外周を覆う覆い部とを有し、前記覆い部と前記大径筒部とは、同径に形成されている。覆い部と大径筒部とが同径とは、覆い部の径寸法と大径筒部の径寸法が同一の場合と、覆い部の径寸法と大径筒部の径寸法が同一でない場合であっても実質的に同一と認定しうる場合を含む。 (4) The outer conductor is composed of a first outer conductor and a second outer conductor attached to the first outer conductor, and the first outer conductor includes the large-diameter tubular portion and the small-diameter tubular portion. and the second outer conductor has the shield connection portion and a cover portion that covers the outer periphery of the small-diameter cylindrical portion, and the cover portion and the large-diameter cylindrical portion are formed to have the same diameter. there is The cover part and the large-diameter cylinder part have the same diameter when the diameter dimension of the cover part and the diameter dimension of the large-diameter cylinder part are the same, and when the diameter dimension of the cover part and the diameter dimension of the large-diameter cylinder part are not the same. This includes cases where it can be recognized as being substantially the same.

つまり、大径筒部よりも小径な小径筒部を覆う覆い部と大径筒部とが同径となっているから、例えば、小径筒部が設けられておらず覆い部が大径筒部よりも大径になる場合に比べて、外導体の体格、ひいてはコネクタの体格が大型化することを抑制できる。 That is, since the large-diameter cylindrical portion and the cover portion covering the small-diameter cylindrical portion having a smaller diameter than the large-diameter cylindrical portion have the same diameter, for example, the small-diameter cylindrical portion is not provided and the cover portion covers the large-diameter cylindrical portion. It is possible to suppress the size of the outer conductor, and thus the size of the connector, from increasing as compared with the case where the diameter is larger than that.

（５）前記小径筒部は、前記大径筒部とは別体に形成され、前記大径筒部内に配置されている。
大径筒部とは別体の小径筒部を大径筒部内に配置するだけで、内導体と小径筒部との間の距離を小さくできる。これにより、相手方コネクタとコネクタとが嵌合後に、相手方コネクタとコネクタとの間においてインピーダンスの不整合が生じることを抑制できる。 (5) The small-diameter tubular portion is formed separately from the large-diameter tubular portion, and is disposed within the large-diameter tubular portion.
The distance between the inner conductor and the small-diameter tubular portion can be reduced simply by arranging the small-diameter tubular portion separate from the large-diameter tubular portion inside the large-diameter tubular portion. Thereby, it is possible to suppress the occurrence of impedance mismatch between the mating connector and the connector after the mating connector and the connector are mated.

（６）前記小径筒部は、前記大径筒部とは別体に形成され、前記小径筒部の一部は、前記大径筒部内に嵌合される。
大径筒部内に相手方外導体と小径筒部の一部とが嵌合することにより、小径筒部と相手方外導体とがほぼ同径となるから、相手方コネクタとコネクタとが嵌合後に、相手方コネクタとコネクタとの間においてインピーダンスの不整合が生じることを抑制できる。 (6) The small-diameter tubular portion is formed separately from the large-diameter tubular portion, and a part of the small-diameter tubular portion is fitted into the large-diameter tubular portion.
By fitting the mating outer conductor and part of the small-diameter cylindrical portion into the large-diameter cylindrical portion, the small-diameter cylindrical portion and the mating outer conductor have substantially the same diameter. Impedance mismatch between connectors can be suppressed.

（７）本開示のコネクタ装置は、前記コネクタと、前記相手方コネクタと、を備えている。 (7) The connector device of the present disclosure includes the connector and the mating connector.

第２シールド接続部６３は、シールド体１５の上半分を覆う半円筒状の上板６４と、上板６４の左右方向両側の側縁に設けられた複数の圧着片６５とを備えている。複数の圧着片６５は、第２外導体６０が第１外導体５１に組み付けられる前の状態では、図４に示されるように、上板６４の左右方向両側の側縁から互いに離れるように斜め下方向に向かって真っ直ぐ延出されている。複数の圧着片６５は、第２外導体６０が第１外導体５１に組み付けられると、複数の圧着片６５が図１および図２に示されるように、シールド体１５の下方に配置された第１シールド接続部５６と共にシールド体１５に巻き付くように圧着固定される。 The second shield connection portion 63 includes a semicylindrical upper plate 64 that covers the upper half of the shield body 15 and a plurality of crimping pieces 65 provided on both side edges of the upper plate 64 in the left-right direction.

［ハウジング８０］
ハウジング８０は、合成樹脂製であって、外導体５０を後方から収容する収容部８２を有している。
収容部８２は、図１から図４に示されるように、前後方向に貫通して形成されている。収容部８２内には、覆い部６１に設けられた貫通孔６１Ａに嵌まり込む端子係止部８３が設けられている。 [Housing 80]
The housing 80 is made of synthetic resin and has an accommodating portion 82 that accommodates the outer conductor 50 from behind.
As shown in FIGS. 1 to 4, the accommodating portion 82 is formed so as to penetrate in the front-rear direction. A terminal locking portion 83 that fits into the through hole 61A provided in the cover portion 61 is provided in the accommodation portion 82 .

端子係止部８３は、外導体５０が収容部８２の正規収容位置に収容されると、図１および図２に示されるように、貫通孔６１Ａに嵌まり込む。したがって、端子係止部８３と貫通孔６１Ａの縁部とが係止することによって外導体５０がハウジング８０内に保持されている。 When the outer conductor 50 is housed in the housing portion 82 at the normal housing position, the terminal locking portion 83 is fitted into the through hole 61A as shown in FIGS. 1 and 2 . Therefore, the outer conductor 50 is held in the housing 80 by engaging the terminal engaging portion 83 with the edge of the through hole 61A.

本実施形態は、以上のような構成であって、続いて、雄コネクタ１０の作用および効果について説明する。
例えば、従来型のコネクタ装置において、雌コネクタの雌型内導体を収容する筒状の雌側外導体を、雄コネクタの内導体を収容する筒状の外導体内に嵌合させる場合、外導体が雌側外導体の外側に嵌合する構成となる。したがって、雄コネクタにおける外導体と内導体との距離が、雌コネクタにおける雌側外導体と雌型内導体との距離に比べて大きくなる。 This embodiment is configured as described above, and the action and effect of the male connector 10 will be described next.
For example, in a conventional connector device, when a tubular female outer conductor accommodating a female inner conductor of a female connector is fitted into a tubular outer conductor accommodating an inner conductor of a male connector, the outer conductor is fitted to the outside of the female outer conductor. Therefore, the distance between the outer conductor and the inner conductor in the male connector is larger than the distance between the female outer conductor and the female inner conductor in the female connector.

すると、雄コネクタと雌コネクタとの嵌合後は、雄型コネクタにおけるインピーダンスが、雌型コネクタにおけるインピーダンスに比べて高くなり、雄型コネクタと雌型コネクタと間においてインピーダンスの不整合が生じることが懸念される。 Then, after the male connector and the female connector are mated, the impedance in the male connector becomes higher than the impedance in the female connector, and an impedance mismatch occurs between the male connector and the female connector. Concerned.

そこで、本発明者らは、上記の課題を解決するため、鋭意検討を行った結果、本実施形態の構成を見出した。すなわち、本実施形態は、被覆電線（電線）１２の外周をシールド体１５で覆うケーブル１１に接続された状態で雌コネクタ（相手方コネクタ）１１０と嵌合する雄コネクタ（コネクタ）１０であって、内導体２０と、外導体５０とを備えている。内導体２０は、被覆電線１２の芯線１３に接続された状態で雌コネクタに設けられた雌型内導体（相手方内導体）１２０に接続可能とされている。外導体５０は、大径筒部５３と、小径筒部５４と、シールド接続部５７とを有しており、シールド接続部５７は、シールド体１５に接続される。大径筒部５３は、図１および図２に示されるように、雌コネクタ１１０に設けられた筒状の雌側外導体（相手方外導体）１５０が内部に嵌合可能な筒状に形成され、小径筒部５４は、大径筒部５３よりも小径の筒状に形成されると共に、内導体を収容している。 In order to solve the above problems, the inventors of the present invention have found out the configuration of the present embodiment as a result of intensive studies. That is, the present embodiment is a male connector (connector) 10 that is fitted to a female connector (mating connector) 110 while being connected to a cable 11 whose outer circumference is covered by a shield body 15. It has an inner conductor 20 and an outer conductor 50 . The inner conductor 20 is connectable to a female inner conductor (mating inner conductor) 120 provided in the female connector while being connected to the core wire 13 of the coated wire 12 . The outer conductor 50 has a large-diameter tubular portion 53 , a small-diameter tubular portion 54 , and a shield connection portion 57 , and the shield connection portion 57 is connected to the shield body 15 . As shown in FIGS. 1 and 2, the large-diameter cylindrical portion 53 is formed in a cylindrical shape into which a cylindrical female-side outer conductor (mating outer conductor) 150 provided on the female connector 110 can be fitted. The small-diameter tubular portion 54 is formed in a tubular shape with a diameter smaller than that of the large-diameter tubular portion 53 and accommodates the inner conductor.

大径筒部５３内に雌側外導体１５０が嵌合されるものの、内導体２０は大径筒部５３よりも小径に形成された小径筒部５４内に収容されているから、雌側外導体１５０が内部に嵌合される大径筒部５３に比べて、内導体２０と小径筒部５４との間の距離を小さくできる。つまり、内導体２０と小径筒部５４との間の距離を、雌型内導体１２０と雌側外導体１５０との間の距離に近づけることができ、雌コネクタ１１０と雄コネクタ１０との嵌合後に、雌コネクタ１１０と雄コネクタ１０との間においてインピーダンスの不整合が生じることを抑制できる。 Although the female-side outer conductor 150 is fitted in the large-diameter tubular portion 53, the inner conductor 20 is housed in the small-diameter tubular portion 54 formed to have a diameter smaller than that of the large-diameter tubular portion 53. The distance between the inner conductor 20 and the small-diameter tubular portion 54 can be reduced compared to the large-diameter tubular portion 53 in which the conductor 150 is fitted. In other words, the distance between the inner conductor 20 and the small-diameter cylindrical portion 54 can be made close to the distance between the female inner conductor 120 and the female outer conductor 150, and the fitting between the female connector 110 and the male connector 10 can be achieved. Impedance mismatch between the female connector 110 and the male connector 10 can be suppressed later.

小径筒部５４と雌側外導体１５０とは、同径に形成されている。小径筒部５４と雌側外導体１５０とが同径となっているから、内導体２０と小径筒部５４との間の距離と、雌型内導体１２０と雌側外導体１５０との間の距離とを同じにすることができる。これにより、雌コネクタ１１０と雄コネクタ１０との嵌合後に、雌コネクタ１１０と雄コネクタ１０との間においてインピーダンスの不整合が生じることをさらに抑制できる。 The small-diameter tubular portion 54 and the female-side outer conductor 150 are formed to have the same diameter. Since the small-diameter cylindrical portion 54 and the female outer conductor 150 have the same diameter, the distance between the inner conductor 20 and the small-diameter cylindrical portion 54 and the distance between the female inner conductor 120 and the female outer conductor 150 are distance can be the same. Thereby, it is possible to further suppress the occurrence of impedance mismatch between the female connector 110 and the male connector 10 after the female connector 110 and the male connector 10 are mated.

小径筒部５４は、大径筒部５３における雌コネクタ１１０側とは反対側の後端部に連なっている。大径筒部５３と小径筒部５４とが連なって一体となっているから、例えば、大径筒部と小径筒部とが別体に構成される場合に比べて、部品点数を低減できる。これにより、雄コネクタの組み立て作業性を向上させることができる。 The small-diameter tubular portion 54 continues to the rear end portion of the large-diameter tubular portion 53 on the side opposite to the female connector 110 side. Since the large-diameter tubular portion 53 and the small-diameter tubular portion 54 are continuous and integrated, the number of parts can be reduced compared to, for example, the case where the large-diameter tubular portion and the small-diameter tubular portion are configured separately. As a result, workability in assembling the male connector can be improved.

外導体５０は、第１外導体５１と、第１外導体５１に組み付けられる第２外導体６０とによって構成され、第１外導体５１は、大径筒部５３と、小径筒部５４とを有し、第２外導体６０は、シールド接続部５７と、小径筒部５４の外周を覆う覆い部６１とを有し、覆い部６１と大径筒部５３とは、同径に形成されている。 The outer conductor 50 is composed of a first outer conductor 51 and a second outer conductor 60 attached to the first outer conductor 51. The first outer conductor 51 has a large-diameter tubular portion 53 and a small-diameter tubular portion 54. The second outer conductor 60 has a shield connection portion 57 and a cover portion 61 that covers the outer periphery of the small-diameter cylindrical portion 54. The cover portion 61 and the large-diameter cylindrical portion 53 are formed to have the same diameter. there is

大径筒部５３よりも小径な小径筒部５４を覆う覆い部６１と大径筒部５３とが同径となっているから、例えば、小径筒部が設けられておらず覆い部が大径筒部よりも大径になる場合に比べて、外導体５０の体格、ひいては雄コネクタ１０の体格が大型化することを抑制できる。 Since the cover portion 61 covering the small-diameter portion 54 having a smaller diameter than the large-diameter portion 53 and the large-diameter portion 53 have the same diameter, for example, the small-diameter portion is not provided and the cover portion has a large diameter. Compared to the case where the diameter is larger than that of the cylindrical portion, it is possible to suppress the size of the outer conductor 50 and thus the size of the male connector 10 from increasing.

＜実施形態２＞
次に、実施形態２について図８および図９を参照して説明する。
実施形態２における雄コネクタ２１０の外導体２５０は、実施形態１における第１外導体５１の形状を変更すると共に、第３外導体２７０を有するものであって、実施形態１と共通する構成、作用、および効果については重複するため、その説明を省略する。また、実施形態１と同じ構成については同一の符号を用いるものとする。 <Embodiment 2>
Next, Embodiment 2 will be described with reference to FIGS. 8 and 9. FIG.
The outer conductor 250 of the male connector 210 according to the second embodiment has a shape different from that of the first outer conductor 51 according to the first embodiment, and has a third outer conductor 270, and has the same configuration and operation as those of the first embodiment. , and effects are duplicated, so the description thereof is omitted. Moreover, the same code|symbol shall be used about the same structure as Embodiment 1. FIG.

実施形態２の外導体２５０は、図８および図９に示されるように、誘電体３０を内部に収容する第１外導体２５１と、第１外導体２５１およびケーブル１１のシールド体１５の外周を覆うように第１外導体２５１に組み付けられる第２外導体２６０と、第１外導体２５１と誘電体３０との間に配置される別体の第３外導体２７０とを備えている。 As shown in FIGS. 8 and 9, the outer conductor 250 of the second embodiment includes a first outer conductor 251 that accommodates the dielectric 30 inside, and the outer circumference of the first outer conductor 251 and the shield body 15 of the cable 11. It comprises a second outer conductor 260 attached to the first outer conductor 251 so as to cover it, and a separate third outer conductor 270 arranged between the first outer conductor 251 and the dielectric 30 .

第１外導体２５１は、角筒型の接続筒部２５２と、接続筒部２５２の下側後端縁に設けられた第１シールド接続部５６とを備えている。
接続筒部２５２は、前後方向に全長にわたって同径に形成されている。接続筒部２５２の前部は、図９に示されるように、雌コネクタ１１０の雌側外導体１５０における筒状接続部１５２が内部に嵌合可能とされている。つまり、外導体２５０における接続筒部２５２は、雌側外導体１５０における筒状接続部１５２よりも大径の大径筒部２５３として形成されている。 The first outer conductor 251 includes a rectangular tube-shaped connection tube portion 252 and a first shield connection portion 56 provided at the lower rear edge of the connection tube portion 252 .
The connection tube portion 252 is formed to have the same diameter over the entire length in the front-rear direction. As shown in FIG. 9, the front portion of the connection tubular portion 252 is adapted to fit inside the tubular connection portion 152 of the female outer conductor 150 of the female connector 110 . In other words, the connecting tubular portion 252 of the outer conductor 250 is formed as a large-diameter tubular portion 253 having a larger diameter than the tubular connecting portion 152 of the female outer conductor 150 .

第２外導体２６０は、覆い部２６１の形状の一部が、実施形態１の覆い部６１とやや異なるものの、構成はほぼ同じであるため、説明を省略する。 The second outer conductor 260 is slightly different from the cover portion 61 of the first embodiment in a part of the shape of the cover portion 261, but the configuration is almost the same, so the explanation is omitted.

第３外導体２７０は、図８に示されるように、導電性を有する金属板材を加工することによって前後方向に貫通する角筒型に形成されている。第３外導体２７０は、第１外導体２５１における接続筒部２５２内に後方から収容可能とされている。第３外導体２７０は、図９に示されるように、雌側外導体１５０における筒状接続部１５２と同径に形成されると共に、内部に誘電体３０が後方から収容可能となっている。 As shown in FIG. 8, the third outer conductor 270 is formed into a rectangular tubular shape penetrating in the front-rear direction by processing a conductive metal plate material. The third outer conductor 270 can be accommodated from the rear inside the connecting tubular portion 252 of the first outer conductor 251 . As shown in FIG. 9, the third outer conductor 270 is formed to have the same diameter as the cylindrical connecting portion 152 of the female outer conductor 150, and the dielectric 30 can be accommodated therein from behind.

第３外導体２７０内に誘電体３０が収容されると、図９に示されるように、第３外導体２７０と内導体２０における箱部２３との間の距離Ｌ２１は、接続筒部２５２と雄型接続部２２との間の距離よりも小さく、かつ雌型内導体１２０における端子接続部１２２と雌側外導体１５０との間の距離Ｌ２と同一となっている。したがって、実施形態２では、第３外導体２７０が、外導体２５０の小径筒部２５４として形成されている。 When the dielectric 30 is accommodated in the third outer conductor 270, as shown in FIG. 9, the distance L21 between the third outer conductor 270 and the box portion 23 of the inner conductor 20 is It is smaller than the distance between the male connection portion 22 and the same as the distance L2 between the terminal connection portion 122 of the female inner conductor 120 and the female outer conductor 150 . Therefore, in Embodiment 2, the third outer conductor 270 is formed as the small-diameter tubular portion 254 of the outer conductor 250 .

つまり、実施形態２では、大径筒部３５３を構成する第１外導体２５１の接続筒部２５２内に小径筒部２５４を構成する第３外導体２７０を収容しているから、接続筒部２５２である内に雌側外導体１５０が嵌合されるものの、内導体２０と第３外導体２７０との間の距離を小さくできるようになっている。これにより、雌コネクタ１１０と雄コネクタ２１０との嵌合後に、雌コネクタ１１０と雄コネクタ２１０との間においてインピーダンスの不整合が生じることを抑制できるようになっている。 That is, in the second embodiment, the third outer conductor 270 forming the small-diameter tubular portion 254 is accommodated in the connecting tubular portion 252 of the first outer conductor 251 forming the large-diameter tubular portion 353 . Although the female-side outer conductor 150 is fitted within this period, the distance between the inner conductor 20 and the third outer conductor 270 can be reduced. Thus, it is possible to suppress impedance mismatch between the female connector 110 and the male connector 210 after the female connector 110 and the male connector 210 are mated.

＜実施形態３＞
次に、実施形態３について図１０および図１１を参照して説明する。
実施形態３における雄コネクタ３１０の外導体３５０は、実施形態１における第１外導体５１の形状を変更すると共に、第３外導体３７０を有するものであって、実施形態１と共通する構成、作用、および効果については重複するため、その説明を省略する。また、実施形態１と同じ構成については同一の符号を用いるものとする。 <Embodiment 3>
Next, Embodiment 3 will be described with reference to FIGS. 10 and 11. FIG.
The outer conductor 350 of the male connector 310 in the third embodiment has the shape of the first outer conductor 51 in the first embodiment, and has a third outer conductor 370, and has the same configuration and operation as in the first embodiment. , and effects are duplicated, so the description thereof is omitted. Moreover, the same code|symbol shall be used about the same structure as Embodiment 1. FIG.

実施形態３の外導体３５０は、図１０および図１１に示されるように、誘電体３０を内部に収容する第１外導体３５１と、実施形態１における第２外導体６０と、第１外導体３５１の前端部が内部に嵌合される別体の第３外導体３７０とを備えている。 As shown in FIGS. 10 and 11, the outer conductor 350 of the third embodiment includes a first outer conductor 351 that accommodates the dielectric 30 inside, the second outer conductor 60 of the first embodiment, and the first outer conductor The front end of 351 is provided with a separate third outer conductor 370 fitted therein.

第１外導体３５１は、角筒型の接続筒部３５２と、接続筒部３５２の下側後端縁に設けられた第１シールド接続部５６とを備えている。
接続筒部３５２は、実施形態１のおける接続筒部５２によりも短く形成されると共に、前後方向に全長にわたって雌側外導体１５０における筒状接続部１５２と同径に形成されている。接続筒部３５２の内部には、誘電体３０が後方から収容可能となっている。誘電体３０が接続筒部３５２内に収容されると、図１１に示されるように、接続筒部３５２と内導体２０における箱部２３との間の距離Ｌ３１は、雌型内導体１２０における端子接続部１２２と雌側外導体１５０との間の距離Ｌ２と同一となっている。したがって、実施形態３では、第１外導体３５１の接続筒部３５２が、外導体３５０の小径筒部３５４として形成されている。 The first outer conductor 351 includes a rectangular tube-shaped connection tube portion 352 and a first shield connection portion 56 provided at the lower rear edge of the connection tube portion 352 .
The connecting tubular portion 352 is formed shorter than the connecting tubular portion 52 in the first embodiment, and has the same diameter as the tubular connecting portion 152 of the female outer conductor 150 over the entire length in the front-rear direction. The dielectric 30 can be accommodated from behind inside the connection tube portion 352 . When the dielectric 30 is housed in the connecting tube portion 352, the distance L31 between the connecting tube portion 352 and the box portion 23 of the inner conductor 20 is equal to that of the terminal of the female inner conductor 120, as shown in FIG. It is the same as the distance L2 between the connecting portion 122 and the female outer conductor 150 . Therefore, in Embodiment 3, the connection tubular portion 352 of the first outer conductor 351 is formed as the small-diameter tubular portion 354 of the outer conductor 350 .

第２外導体６０は、第１外導体３５１およびケーブル１１のシールド体１５の外周を覆うように第１外導体３５１に組み付けられる。 The second outer conductor 60 is attached to the first outer conductor 351 so as to cover the outer circumference of the first outer conductor 351 and the shield body 15 of the cable 11 .

第３外導体３７０は、図１０に示されるように、導電性を有する金属板材を加工することによって前後方向に貫通する角筒型に形成されている。第３外導体３７０における後端部の内側には、図１１に示されるように、第１外導体３５１における接続筒部３５２の前端部（一部）が後方から嵌合可能とされている。一方、第３外導体３７０内の接続筒部３５２よりも前方には、雌側外導体１５０における筒状接続部１５２が前方から嵌合可能とされている。つまり、第３外導体３７０は、外導体３５０の大径筒部３５３として形成されている。また、第３外導体３７０は、図１１に示されるように、接続筒部３５２の外周に配置される第２外導体６０の覆い部６１と同径に形成されている。 As shown in FIG. 10, the third outer conductor 370 is formed into a rectangular tubular shape that penetrates in the front-rear direction by processing a conductive metal plate material. As shown in FIG. 11, the front end (a portion) of the connecting tube portion 352 of the first outer conductor 351 can be fitted from behind inside the rear end of the third outer conductor 370 . On the other hand, the cylindrical connecting portion 152 of the female outer conductor 150 can be fitted from the front forward of the connecting cylindrical portion 352 in the third outer conductor 370 . That is, the third outer conductor 370 is formed as the large-diameter tubular portion 353 of the outer conductor 350 . 11, the third outer conductor 370 is formed to have the same diameter as the covering portion 61 of the second outer conductor 60 arranged on the outer periphery of the connecting tubular portion 352. As shown in FIG.

したがって、雄コネクタ３１０と雌コネクタ１１０とが嵌合されると、図１１に示されるように、外導体３５０における第３外導体３７０内において接続筒部３５２と雌側外導体１５０の筒状接続部１５２とが前後方向に突き合わされた状態となる。 Therefore, when the male connector 310 and the female connector 110 are mated, as shown in FIG. 152 are abutted in the front-rear direction.

つまり、実施形態３では、大径筒部３５３を構成する外導体３５０の第３外導体３７０内に、内導体２０を収容する小径筒部３５４と雌側外導体１５０とが嵌合されることにより、小径筒部３５４と雌側外導体１５０とがほぼ同径となる。すなわち、内導体２０と接続筒部３５２との間の距離Ｌ３１と、端子接続部１２２と雌側外導体１５０との間の距離Ｌ２とをほぼ同一にすることができ、雌コネクタ１１０と雄コネクタ３１０との嵌合後に、雌コネクタ１１０と雄コネクタ３１０との間においてインピーダンスの不整合が生じることを抑制できるようになっている。 That is, in the third embodiment, the small-diameter cylindrical portion 354 accommodating the inner conductor 20 and the female-side outer conductor 150 are fitted in the third outer conductor 370 of the outer conductor 350 forming the large-diameter cylindrical portion 353. As a result, the small-diameter cylindrical portion 354 and the female-side outer conductor 150 have substantially the same diameter. That is, the distance L31 between the inner conductor 20 and the connecting tube portion 352 and the distance L2 between the terminal connecting portion 122 and the female outer conductor 150 can be made substantially the same, so that the female connector 110 and the male connector After mating with the female connector 110 and the male connector 310 , it is possible to suppress the occurrence of impedance mismatch between the female connector 110 and the male connector 310 .
